Outline of operation
● When the ZRST instruction is executed, all the running processes within the range from the
process [D1] and [D2] will be cleared.
● It can also be used to reset (clear to zero) the range from the area (bit address) specified in
[D1] to the area (bit address) specified in [D2].
■
Precautions for programming
● Be sure that [D1] is smaller than [D2].
● This instruction can be executed from the normal ladder area as well as a running process.
